How to use the online alarm clock
You’re finishing up and heading out to collect your teenager from Army Cadets when the 9:35 pm alarm sounds. It marks the moment to put things away, pick up your keys and leave, rather than letting another small job delay you. With 10:00 pm approaching, the alert gives you a clear break point before the collection time.
Before leaving for the Army Cadets pickup, check where your browser’s audio is being sent. Headphones can remain connected after you have taken them off, leaving the alarm audible only through earpieces on a desk or in a bag. A quick test sound can confirm that the alert will come from the phone or computer speaker you expect. Keep the browser running and the phone or computer awake; otherwise the Army Cadets collection alarm cannot sound and you may set off late.
Collecting a cadet at 9:35 pm may mean quieter streets than during the evening rush, but the journey can still vary around town centres, roadworks or late events. Check the route before you finish what you are doing, then allow a few spare minutes for the drive and somewhere safe to stop. Having your coat, keys and pickup details together makes it easier to leave promptly when the alarm goes.
Common questions
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
